Hair Follicle Drug Testing - Mountville, PA

What it is, How it works

Hair analysis is now recognized as a robust method for identifying alcohol and drug consumption. Hair serves as a long-term record for substances by embedding biomarkers in its strands as they grow. When hair is sampled near the scalp, it offers approximately a 3-month detection period for substances. The collection process is straightforward, relatively tamper-proof, and simple to transport.

A 1.5-inch section of approximately 200 hair strands (about the thickness of a #2 pencil) from near the scalp yields 100mg of hair, which is the optimal sample for both screening and confirmation. For tests like EtG, additional analyses, or those exceeding 10 panels, 150mg of the sample is suggested. It's advisable to measure the sample using a jeweler’s scale. If no scalp hair is accessible, an equivalent amount of body hair can be retrieved. "Head hair" pertains solely to scalp hair, while "body hair" includes all other types (such as facial and axillary hair).

Process Overview

Processing a drug test result in a lab involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary entry of a sample into the lab system, ensuring the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not available from an electronic chain of custody.

Screening provides an initial brief assessment for drug presence. Though Screening is economical for excluding drug use in most samples, a positive result demands confirmation for legal validity. Samples presumptively positive in Screening necessitate further confirmation.

A presumptively positive sample in Screening leads to additional hair being taken from the initial collection for Extraction. During Extraction, drugs are isolated from hair at much lower levels than other methods (ex. urine or oral fluid), explaining why hair drug analysis is notoriously challenging.

GC/MS, GC/MS/MS, or LC/MS/MS methods are employed for confirming positive screenings. Prior to confirmation, all presumptive positives are cleaned as required. The complete lab process, from Accessioning through Confirmation, complies with standards set by the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests track drug use for up to 90 days, while urine tests cover shorter periods.
• Hard to manipulate: Cheating is quite difficult, enhancing the reliability of results.
• Tracks historical use: Offers a timeline of drug use rather than just a snapshot of recent activity.

Limitations:

• Not for recent consumption: Drugs become detectable in hair only after about 5-7 days.
• Expense: These tests are typically pricier than other methods.
• Result variability: Aspects like hair color or individual hair growth rates can influence metabolite concentrations.

Note: Commonly called "hair follicle tests," this analysis assesses the hair strand, not the scalp's hair follicle

Why Hair Follicle Testing Beats Urine Testing

In Mountville, PA, hair follicle testing presents a significant advantage over urine tests. Hair tests detect drug use within a 90-day window, offering superior accuracy and dependability. In contrast, urine tests have a limited detection period, which may not fully capture past drug use. This broader window allows employers and officials a more comprehensive view of substance histories.

Extended Detection Window

Hair follicle testing in Mountville, PA provides an extended detection window, covering up to 90 days of substance use. This long detection period aids employers in assessing the full scope of a candidate's or employee's past substance use, offering an all-encompassing view that short-term methods like urine tests may not provide. It uncovers patterns and timelines of use, enhancing the screening process.

Tamper-Resistant Testing Method

Employers in Mountville, PA trust hair follicle testing for its tamper-resistant nature. Hair samples are collected through a supervised process, minimizing the risk of sample adulteration. This secure methodology ensures that the test results remain unquestionable and dependable, providing peace of mind and reliability in knowing the results reflect true substance use.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
